Most 10 year old kids don’t grow up with the use a full chemistry lab in the basement and a copy of ‘Fortunes Formula’ to help them dabble in pyrotechnics. It’s also not usual as you progress to teenage years to have an older brother willing to buy you one of the first commercially available personal computers in the late 1970’s. It’s also arguably not conventional to grow up in a family culture imbued with the expectation that if something breaks, like the TV, you fix it yourself.
